Haram Family & relations
The Quran lists the women a man may not marry because of blood, marriage and nursing relationships, such as mothers, daughters, sisters and aunts (4:23), and it forbids marrying women whom one's father had married (4:22).
وَلَا تَنكِحُوا۟ مَا نَكَحَ ءَابَآؤُكُم مِّنَ ٱلنِّسَآءِ إِلَّا مَا قَدْ سَلَفَ ۚ إِنَّهُۥ كَانَ فَٰحِشَةًۭ وَمَقْتًۭا وَسَآءَ سَبِيلًا ﴿٢٢﴾
Wala msiwaoe wake walio waoa baba zenu, ila yaliyo kwisha pita. Hakika huo ni uchafu na uchukizo na ni njia mbaya.
حُرِّمَتْ عَلَيْكُمْ أُمَّهَٰتُكُمْ وَبَنَاتُكُمْ وَأَخَوَٰتُكُمْ وَعَمَّٰتُكُمْ وَخَٰلَٰتُكُمْ وَبَنَاتُ ٱلْأَخِ وَبَنَاتُ ٱلْأُخْتِ وَأُمَّهَٰتُكُمُ ٱلَّٰتِىٓ أَرْضَعْنَكُمْ وَأَخَوَٰتُكُم مِّنَ ٱلرَّضَٰعَةِ وَأُمَّهَٰتُ نِسَآئِكُمْ وَرَبَٰٓئِبُكُمُ ٱلَّٰتِى فِى حُجُورِكُم مِّن نِّسَآئِكُمُ ٱلَّٰتِى دَخَلْتُم بِهِنَّ فَإِن لَّمْ تَكُونُوا۟ دَخَلْتُم بِهِنَّ فَلَا جُنَاحَ عَلَيْكُمْ وَحَلَٰٓئِلُ أَبْنَآئِكُمُ ٱلَّذِينَ مِنْ أَصْلَٰبِكُمْ وَأَن تَجْمَعُوا۟ بَيْنَ ٱلْأُخْتَيْنِ إِلَّا مَا قَدْ سَلَفَ ۗ إِنَّ ٱللَّهَ كَانَ غَفُورًۭا رَّحِيمًۭا ﴿٢٣﴾
Mmeharimishiwa mama zenu, na binti zenu, na dada zenu, na shangazi zenu, na khaalati zenu, na binti wa ndugu mume, na binti wa dada, na mama zenu walio kunyonyesheni, na dada zenu kwa kunyonya, na mama wa wake zenu, na watoto wenu wa kambo walio katika ulinzi wenu walio zaliwa na wake zenu mlio waingilia. Ikiwa hamkuwaingilia basi hapana lawama juu yenu. (Pia mmeharimishwa) wake wa watoto wenu walio toka katika migongo yenu. Na kuwaoa pamoja dada wawili isipo kuwa yale yaliyo kwisha pita. Hakika Mwenyezi Mungu ni Mwenye kusamehe Mwenye kurehemu.
